Forward slepless transmission device and method

Abstract

The invention relates to a power actuated forward stepless speed change device and a method thereof. The device comprises a stepless speed change device and a double-torque transmission gear; wherein the stepless speed change device comprises a differential gear train or comprises an input central shaft, an output central shaft and a differential element; the double-torque transmission gear comprises a driving wheel, a drive shaft, a lever cambered axle, a universal transmission bearing seat, a resistance shaft, a stepless speed regulating device, and a driven wheel; under a certain power, a power source torque acts on the two mutually vertical axis directions of the double-torque transmission gear; one axis direction leads the stepless speed change device to output a torque to the outside; the other axis direction realizes running at constant speed in a way that the resultant external torque generated by the double-torque transmission gear, the stepless speed change device and a loadis zero. Forward stepless speed change can be realized by adjusting the transmission ratio of the double-torque transmission gear. The device has higher efficiency, can effectively save energy and save the manufacturing cost, can be used as the stepless speed change device, and can be broadly applied to various mechanical devices.

[0002] The friction continuously variable transmission in the prior art is the same as other transmissions or reducers. When the constant power is input, after starting, it can run at a constant speed at any time during the acceleration operation. The friction between the input wheel and the driven wheel of the continuously variable transmission Due to the existence of a pair of internal moments of equal magnitude and opposite directions, the angular momentum between the input wheel and the driven wheel is transferred in the same amount, and the internal moment and the output torque correspond to each other, which constitutes the transmission condition of the friction continuously variable transmission. The friction between the input wheel and the output wheel The movement is the interaction between the internal torque and the output torque reaction torque. Since the reaction torque of the output torque and the relative internal torque angular impulse are combined to zero, the total external force is zero, and uniform speed operation can be realized; the friction continuously variable transmission is a friction transmission.
